Millions of Gallons Annually

Annual Water Consumption


Located in the mid-Atlantic United States, this 51,600 ft² senior living facility specializes in Alzheimer’s care, hospice relationships, and short terms stays. Due to the specific needs of the residents, maintaining their comfort was a priority in the project

  • The existing light fixtures and exit signs in the back-of-house were original to the building and are no longer being manufactured

  • The faucets throughout the building operated at an outdated EPA standard of 2.2 GPM.

Our Solution

Green Generation Solutions installed high efficiency LED fixtures and industrial strip de-lamping kits in the back-of-house areas and installed occupancy sensors to increase the overall efficiency of the lighting system.

  • GreenGen installed faucet pressure aerators in order to minimize the waste of water in the guest rooms, common area bathrooms, and back of house locations. The water flow was reduced from 2.2 GPM to 0.5 GPM, resulting in a measured 77% decrease in water consumption

  • Vending machine controls were installed to reduce the machines’ energy consumption. The controls work with occupancy sensors to allow the machine compressors to cycle off and lights to shut down when not in use

  • GreenGen installed three light loggers in rooms where occupancy sensors had been installed to measure light runtimes before and after installation in order to verify the solution savings. The average reduction per room was a 56% decrease in runtimes for the light fixtures

  • GreenGen coordinated all rebate capture activities with the state utility to secure funding for nearly 22% of the total project cost
